Priority access license holder protection

ABSTRACT

According to one configuration, a communication management resource in a wireless network environment records a location of a wireless base station. The communication management resource then defines a region of wireless coverage provided by the wireless base station based on feedback received from the wireless base station. For example, in one arrangement, the user equipment provides performance metrics to the wireless base station. The wireless base station uses the performance metrics to determine boundaries associated with a region of wireless coverage provided by the wireless base station. The wireless base station communicates the boundary information to the communication management resource. Subsequent to identifying the location of the wireless base station and defining the determined region of wireless coverage associated with the wireless base station, the communication management resource then controls allocation of wireless bandwidth in a vicinity of the region of wireless coverage to protect the wireless base station from interference.

BACKGROUND

Conventional wireless networks typically include one or more wireless base stations to provide mobile communication devices access to a remote network such as the Internet. One type of wireless base station is a so-called CBSD (Citizen Broadband Radio Service Device). Such a device uses a wireless channel allocated from a CBRS (Citizens Band Radio Service) band to support communications with one or more mobile communication devices.

Typically, so-called SAS (Spectrum Access Service) in a CBRS network allocates one or more wireless channels to a CBSD (such as a wireless base station) to support communications with respective user equipment such as one or more mobile communication devices. Each base station can be configured to communicate with the SAS to receive notification of the one or more wireless channels allocated for its use. Controlled allocation of wireless channels by the spectrum access system helps to prevent interference.

There are multiple different types of wireless channels in a conventional CBRS band. For example, portions of bandwidth in a CBRS band include so-called Priority Access License (PAL) wireless channels, General Authorized Access (GAA) wireless channels, or a combination of both.

In general, PAL wireless channels are licensed wireless channels in which a corresponding licensee (such as an entity paying for use of the wireless channel) is provided some protection of use. For example, when no incumbent user requires use of the channels, the licenses entity is able to freely use the PAL wireless channels in respective one or more predetermined geographical regions without interference by other users (such as lower priority GAA users).

Subsequent to allocation, the wireless base station then uses the allocated bandwidth to provide one or more communication devices access to a remote network such as the Internet.

BRIEF DESCRIPTION OF EMBODIMENTS

There are deficiencies associated with conventional techniques of determining regions of geographical coverage associated with licensed users and corresponding wireless channels.

For example, conventional techniques do not provide an accurate way of identifying an actual corresponding geographical region of protection to be afforded to licensed entities. The result is that either the PAL entity paying for use of respective licensed wireless channels may experience interference if the conventional determined region of protection provided by a spectrum access system is too small. Conversely, if the region of protection afforded by the spectrum access system to a licensed entity is too large, the available bandwidth is not used to its fullest potential.

Certain embodiments herein solve the problem of area (region of wireless coverage) determination in which priority spectrum license holders are protected. For example, the protected areas as described herein are called PAL protection areas (PPAs).

Currently there is no specific method of creating an accurate PPA in a network environment. Embodiments herein propose a novel method to create PPAs (PAL protection areas) in a CBRS network based on any combination of UE measurements, CBSD location, and CBSD performance counters & KPIs.

Thus, embodiments herein provide novel ways of providing improved use of wireless channels amongst different entities sharing use of bandwidth in a wireless network environment.

More specifically, according to one example embodiment, a communication management resource tracks and records a location of a wireless base station in a network environment. The communication management resource defines a region of wireless coverage provided by the wireless base station based on input (feedback) received from the wireless base station. Subsequent to defining the location and region of wireless coverage associated with the wireless base station, the communication management resource (such as a spectrum access system) then controls allocation of wireless bandwidth in a vicinity of the region of wireless coverage.

In one embodiment, the controlled allocation of bandwidth by the communication management resource in the vicinity of the region of wireless coverage provided by the wireless base station protects use of wireless channels licensed to a respective service provider operating the wireless base station to provide wireless coverage to user equipment in the region of wireless coverage. For example, the controlled allocation of bandwidth in the vicinity of the region of wireless coverage provided by the wireless base station reduces wireless interference between the wireless base station and user equipment in communication with the wireless base station.

The input from the wireless base station can include any suitable information. For example, in one embodiment, the input is generated by the wireless base station based upon wireless link performance metrics provided by user equipment in communication with the wireless base station. The input provides an indication of the wireless coverage region provided by the corresponding wireless base station.

In accordance with still further embodiments, the licensed channels assigned to the wireless base station are wireless channels allocated from a CBRS (Citizen Band Radio Service) spectrum.

In accordance with further embodiments, defining the region of wireless coverage provided by the wireless base station based on the input received from the wireless base station includes: via the input, identifying a distance between the wireless base station and user equipment in wireless communication with the wireless base station. The identified distance provides an indication of a current region of wireless coverage associated with the wireless base station.

Further embodiments herein include defining and determining the region of wireless coverage provided by the wireless base station based at least in part on a level of wireless interference experienced by user equipment in communication with the wireless base station.

In yet further embodiments, the wireless base station provides the input in response to detecting that user equipment in communication with the wireless base station detects wireless interference associated with the wireless channels licensed to the wireless base station. Because the channels are licensed, the service provider paying for such licensed PAL wireless channels has an expectation of little or no wireless interference by GAA wireless channel users. The user equipment communicates occurrence of the interference to the wireless base station. The wireless base station generates and/or stores metrics indicating occurrence of the interference in one or more communications to the communication management resource.

In yet further embodiments, tracking the location of the wireless base station includes: receiving location information from the wireless base station, the location information indicating the location of the wireless base station in the network environment; and providing a mapping between the location of the wireless base station and the wireless channels licensed to the wireless base station.

It is noted that use of unlicensed wireless channels in a vicinity of the wireless base station can cause wireless interference. According to further embodiments, controlling allocation of wireless bandwidth in the vicinity of the region of wireless coverage includes: controlling allocation of unlicensed wireless channels in the network environment in or around a vicinity of the wireless base station, the controlled allocation of the unlicensed wireless channels reducing interference with the licensed wireless channels.

In accordance with yet further embodiments, a wireless base station monitors user equipment in communication with the wireless base station. The wireless base station receives feedback from the user equipment; the feedback indicates link quality between the user equipment and the wireless base station. The wireless base station and/or other resource such as the communication management resource defines the region of wireless coverage provided by the wireless base station based on the feedback received from the user equipment. The communication management resource then controls allocation of wireless bandwidth in a vicinity of the region of wireless coverage; the controlled allocation protects use of wireless channels licensed to the wireless base station.

In one embodiment, the link quality for one or more client communication devices (user equipment) indicates a level of wireless interference above a threshold value. In response to detecting that the link quality is above the threshold value, the communication management resource calculates the distance between the wireless base station in the user equipment and then defines the region of wireless coverage based on the calculated distance.

In a similar manner as previously discussed, the licensed channels can be selected from any suitable available wireless spectrum. In one example embodiment, the wireless channels are allocated from a CBRS (Citizen Band Radio Service) spectrum.

In accordance with further embodiments, the allocation management resource grants the wireless base station use of the licensed wireless channels. The wireless base station communicates with user equipment via use of the granted licensed wireless channels. In one embodiment, the input from the wireless base station is based on detected interference of the user equipment receiving communications from the wireless base station over the licensed wireless channels.

As previously discussed, in contrast to conventional techniques of defining a region of wireless coverage associated with a wireless base station, embodiments herein include producing the region of wireless coverage based on user equipment feedback. Determining regions of wireless coverage using input from wireless base stations is useful because it provides a more accurate depiction of a region used by a respective wireless base station. After identifying a region of wireless coverage (based on actual use of the wireless channels) as indicated by the user equipment and/or wireless base station, the communication management resource then controls allocation of licensed and unlicensed wireless channels in the network environment. The controlled allocation of the unlicensed and/or other licensed wireless channels in the vicinity of the determined region of wireless coverage reduces interference with respect to the wireless base station and corresponding supported user equipment.

DETAILED DESCRIPTION

Priority Access License (PAL) holders buy wireless licenses and reserve the right to use them in corresponding pre-determined geographical areas of operation. If there are PLA operators in the CBRS network, the main objection of SAS (Spectrum Access System) is to protect these PLA holders from the interference generated by other users in the network. However, since PAL holders (such as specific network operators) will provide multiple CBSDs (wireless base stations to serve corresponding user equipment). In one embodiment, each of the CBSDs will create a region to be protected from wireless interference so that a respective service provider is able to user equipment licensed wireless channels without experiencing a high level of wireless interference. This region is called PPA.

To provide so-called PAL protection, in accordance with general embodiments herein, a communication management resource in a wireless network environment tracks/records a location of a corresponding wireless base station. The communication management resource (or other suitable resource such as a wireless base station) then defines a region of wireless coverage provided by the wireless base station based on input received from the wireless base station. For example, in one embodiment, the input (indicating a region of wireless coverage provided by a wireless base station) is generated by the wireless base station and/or user equipment based upon wireless link performance metrics provided by user equipment in communication with the wireless base station. Subsequent to identifying the location of the wireless base station and defining the actual (measured) region of wireless coverage associated with the wireless base station, the communication management resource then controls subsequent allocation of wireless bandwidth in a vicinity of the region of wireless coverage to protect the wireless base station from wireless interference.

In contrast to merely using estimation techniques, embodiments herein include determining regions of wireless coverage first respective wireless base stations based at least in part on feedback from user equipment. Techniques as described herein are advantageous because performance metrics from user equipment and/or wireless base stations provide a basis in which to produce a more accurate depiction of the corresponding region of wireless coverage provided by a respective wireless base station.

Now, more specifically, FIG. 1 is an example diagram illustrating a wireless network environment according to embodiments herein.

As shown in this example embodiment, network environment 100 includes communication management resource 140 (such as a spectrum access system), wireless base station 131, user equipment 121-1, user equipment 121-2, user equipment 121-3, user equipment 121-4, wireless base station 132, user equipment 122-1, user equipment 122-2, user equipment 122-3, and network 190 such as the Internet.

Note that each of the resources (such as wireless base station 131, wireless base station 132, user equipment 121, user equipment 122, communication management resource 140, etc., in network environment 100 can be configured to include appropriate hardware, software, or combination of hardware and software to carry out respective operations as discussed herein.

In one embodiment, the communication management resource 140 is a so-called spectrum access system that allocates wireless channels for use by wireless devices (wireless base stations, user equipment, etc.) in the network environment 100.

As shown, the wireless base station 131 provides user equipment 121 (such as user equipment 121-1, user equipment 121-2, user equipment 121-3, user equipment 121-4) wireless access to the remote network 190 over backhaul 175. For example, in an upstream direction, user equipment 121-1 communicates data over a respective wireless communication link to the wireless base station 131; wireless base station 131 then conveys the data over the backhaul 175 to the network 190. In a downstream direction, the backhaul 175 conveys communications from the network 190 destined to the user equipment 121 over the backhaul 175 through the wireless base station 131 to respective target user equipment.

In a similar manner, the wireless base station 132 provides user equipment 122 (such as user equipment 122-1, user equipment 122-2, user equipment 122-3, etc.) wireless access to the remote network 190 over backhaul 175. For example, in an upstream direction, user equipment 122-1 communicates data over a respective wireless communication link to the wireless base station 132; wireless base station 132 conveys the data over the backhaul 175 to the network 190. In a downstream direction, the backhaul 175 conveys communications from the network 190 destined to the user equipment 121 over the backhaul 175 through the wireless base station 131 to respective target user equipment.

In accordance with further embodiments, the communication management resource 140 records a location of wireless base stations in the network environment 100.

In one embodiment, rather than merely estimating a region of wireless coverage provided by a wireless base station, the communication management resource 140 as described herein implements one or more techniques to more accurately define or determine a respective region of wireless coverage of each wireless base station so that wireless base stations are able to use licensed wireless channels without interference from other wireless users. The accurate definition of a respective region of wireless coverage associated with a first wireless base station as described herein ensures that other wireless base stations in a vicinity of the first wireless base station are able to use wireless channels without interference from the first wireless base station and vice versa.

As further shown, to manage wireless communications in the network environment 100, each of the wireless base stations registers with the communication management resource 140 (such as a spectrum access system). For example, in operation #1, via communications 151-1 from the wireless base station 131, the wireless base station 131 notifies the communication management resource 140 of its identity (unique network address=XXZ2) and current location (i.e., location L1). The location information conveyed in communications 151-1 can be conveyed in any suitable format (such as latitude and longitude if desired).

Further, via communications 152-1 from the wireless base station 132, the wireless base station 132 notifies the communication management resource 140 of its identity (unique network address=XXZ3) and current location (i.e., location L2). The location information conveyed in communications 152-1 can be conveyed in any suitable format (such as latitude and longitude if desired).

As an alternative to receiving the location information from the respective wireless base station, note that such information can be received from any suitable resource having knowledge of a location of the respective wireless base station.

FIG. 2 is an example diagram illustrating channel allocation information and service provider information according to embodiments herein.

As shown in FIG. 2, in response to receiving respective communications 151-1 and 151-2, the communication management resource 140 generates PAL (Priority Access License) service provider information 161-1 (stored in repository 180 in FIG. 1), which maps wireless base stations and corresponding identities to locations and corresponding service providers.

More specifically, as shown, the communication management resource 140 maps the wireless base station 131 having network address=XXZ2 to the location L1 and corresponding service provider #1; the communication management resource 140 maps the wireless base station 132 having network address=XXZ3 to the location L2 and corresponding service provider #1; the communication management resource 140 maps the wireless base station 133 having network address=ABX6 to the location L3 and corresponding service provider #2; and so on.

Accordingly, embodiments herein include recording the location of the wireless base stations based on received location information and, as further discussed below, providing a mapping between the location of the wireless base station and the wireless channels licensed to the wireless base station.

Further in this example embodiment, assume that both service provider #1 and service provider #2 are licensed (pay a fee) to use one or more available wireless channels in network environment 100.

In one embodiment, the available wireless channels assigned for use by the communication management resource 140 include wireless channels available in a CBRS (Citizens Band Radio System) frequency band. In such an instance, the communication management resource 140 allocates wireless channels from a CBRS band such as one or more Priority Access License (PAL) wireless channels, one or more General Authorized Access (GAA) wireless channels to different devices (such as wireless base stations 131, 132, or CBSDs) in network environment 100.

Referring again to FIG. 1, in accordance with further embodiments, the communication management resource 140 receives notification of the service provider identity and corresponding general region (such as via license information 163 in FIG. 1) in which each service provider pays fees for a license to use portions of the available wireless spectrum. Note that the license assignment information 163 can be received from any suitable resource having authority to provide such information to the communication management resource 140.

In addition to generating the PAL service provider information 161-1, the communication management resource 140 also creates channel allocation information 162-1 (stored in repository 180 in FIG. 1). As shown, the PAL service provider information 161-1 indicates a mapping of service providers and corresponding wireless channels licensed for use by the different service providers.

As further discussed herein, the communication management resource 140 ensures that the service providers licensing wireless channels in a respective wireless region (so-called PPA or PAL Protection Area) are free to use such channels in their regions of wireless coverage without interference by other wireless users in the network environment 100.

During or after registration of a respective wireless base station with the communication management resource 140 in operation #1, the communication management resource 140 notifies the respective wireless base station of one or more assigned wireless channels.

For example, in operation #2, via communications 171-1, and in accordance with license assignment information 163, the communication management resource 140 notifies the wireless base station 131 that wireless channels #11 and #12 are assigned for use by the wireless base station 131. Via communications 171-2, and in accordance with license assignment information 163 by the channel allocation information 162-1, the communication management resource 140 notifies the wireless base station 131 that wireless channels #11 and #12 are assigned for use by the wireless base station 132; and so on.

Thus, the allocation management resource 140 grants the wireless base stations use of the licensed wireless channels. The wireless base station communicates with user equipment via use of the granted licensed wireless channels.

In one embodiment, the communication management resource 140 allocates any type of wireless channels such as: one or more Priority Access Lease (PAL) wireless channels, General Authorized Access (GAA) wireless channels, or a combination of both.

In this example embodiment, the multiple wireless channels (#11, and #12) assigned by the communication management resource 140 for use by the wireless base station includes wireless channels available in a CBRS (Citizens Band Radio System) frequency band.

Note that the wireless base stations and corresponding user equipment operated in network environment 100 can be configured to communicate in accordance with any suitable wireless communication protocol. In one embodiment, the user equipment in network environment 100 communicates via the LTE (Long Term Evolution) protocol (5G protocol).

Based on the nature of CBRS channels, note that assignment/use of the SAS-allocated channels (such as PAL wireless channels, GAA wireless channels) can be revoked at any time by communication management resource 140 to enable use of the corresponding bandwidth (such as one or more wireless channels) by a higher priority incumbent user such as the government.

Although the communication management resource 140 has general knowledge of the location of each wireless base station 131, 132, etc., further embodiments herein include communicating with each of the wireless base stations to determine an accurate region of wireless coverage provided by each wireless base station as discussed below.

FIG. 3 is an example diagram illustrating wireless base station collection of data from user equipment according to embodiments herein.

As shown in FIG. 3, via operation #3, the service provider #1 provides each of its wireless base stations (such as wireless base station 321, wireless base station 322, etc.) threshold value information to facilitate accurate determination of a respective region of wireless coverage provided by a corresponding wireless base station.

More specifically, service provider #1 transmits communications 311-1 including threshold value information to wireless base station 131. Service provider #2 transmits communications 311-1 including threshold value information to wireless base station 131. Use of the threshold value information to identify boundaries of a respective wireless base station's region of wireless coverage is further discussed below.

Further in this example embodiment, each of the wireless base stations in network environment 100 receives feedback (such as communications 321, 322, etc.) from respective user equipment. The feedback from the user equipment to the wireless base station can include any suitable information.

For example, in one embodiment, the feedback from respective user equipment is or includes wireless link performance metrics generated by the user equipment. The link performance metrics indicate a quality associated with the respective wireless communication link between the user equipment and wireless base station.

More specifically, in this example embodiment, the user equipment 121-1 transmits communications 321-1 (such as link quality performance metrics produced by user equipment 121-1) to the wireless base station 131; the user equipment 121-2 transmits communications 321-2 (such as link quality performance metrics produced by user equipment 121-2) to the wireless base station 131; the user equipment 121-3 transmits communications 321-3 (such as link quality performance metrics produced by 121-3) to the wireless base station 131; the user equipment 121-4 transmits communications 321-4 (such as link quality performance metrics produced by user equipment 121-4) to the wireless base station 131, and so on.

Further, the user equipment 122-1 transmits communications 322-1 (such as link quality performance metrics produced by user equipment 122-1) to the wireless base station 132; the user equipment 122-2 transmits communications 322-2 (such as link quality performance metrics produced by user equipment 122-2) to the wireless base station 132; the user equipment 122-3 transmits communications 322-3 (such as link quality performance metrics produced by user equipment 122-3) to the wireless base station 132; and so on.

In one embodiment, the feedback in respective communications 321, 322 from each respective user equipment includes one or more metrics such as a CQI (Channel Quality Indicator) value, RSRP (Reference Signal Received Power) value, RSRQ (Reference Signal Received Quality) value, RSSI (Received Signal Strength Indicator) value.

The CQI (Channel Quality Indicator) value received from respective user equipment indicates a corresponding quality of the wireless communication link between the respective user equipment sending the CQI value and the wireless base station.

The RSRP (Reference Signal Received Power) value received from respective user equipment indicates is a measure of signal level and quality for modern LTE networks. In general, RSRP is a RSSI-type (received Signal Strength Indicator) of measurement, which indicates the power of the LTE Reference Signals spread over the full bandwidth and narrowband.

The RSRQ (Reference Signal Received Quality) value received from respective user equipment indicates a quality of a received reference signal. RSRQ measurement and calculation is based on RSRP and RSSI. RSRP determines signal quality and RSSI determines co-channel interference and noise.

FIG. 4 is an example diagrams illustrating analysis of data and generation of interference scores for each of the different user equipment according to embodiments herein.

Via operation #5 in FIG. 4, each of the wireless base stations records feedback received from respective user equipment as well as other information (such as a MCS, TBS, user equipment buffer size, average data flow rate of wireless communications between the wireless base station and the user equipment, etc.) associated with the respective user equipment. Wireless base station 131 or other suitable resource records data 431-1. Wireless base station 132 records data 432-1. The MCS value (MCS) is a rough indicator (metric) of wireless bandwidth capability between the user equipment and wireless base station. The TBS value represents a Transport Block Size associated with wireless communications.

Via operation #6, the wireless base station or other suitable resource generates an interference score (431-2 and 432-2) for the respective user equipment.

Results of wireless base station operations #5 and #6 are shown in FIG. 5.

FIG. 5 is an example diagram illustrating mapping of user equipment data, wireless link information, and corresponding interference scores associated with different user equipment different according to embodiments herein.

As shown in FIG. 5, the wireless base station 131 or other suitable resource records information associated with the different user equipment.

For example, the wireless base station 131 produces record 531-1 to include feedback (link quality metrics) generated by user equipment 121-1 such as CQI (Channel Quality Indicator) value, RSRP (Reference Signal Received Power) value, RSRQ (Reference Signal Received Quality) value, RSSI (Received Signal Strength Indicator) value.

In addition to storing such feedback (link quality metrics) from user equipment 121-1, the wireless base station 131 produces the record 531-1 to include additional information such as MCS, TBS, user equipment buffer size, average data flow rate, etc.

As previously discussed, the MCS value (MCS) is a rough indicator (metric) of wireless bandwidth capability between the respective user equipment and wireless base station. The TBS (Transport Block Size) value is a metric representing a Transport Block Size associated with wireless communications between the user equipment and the wireless base station 131.

As further discussed below, a processing resource (such as hardware or software) in the wireless base station or other suitable device produces an interference score based on the information in each record. In one embodiment, the interference score is a binary value such as either a high interference score or a low interference score. Alternatively, the interference score is a numerical value indicating a degree to which the respective user equipment experiences wireless interference.

Further in this example embodiment, via one or more of the settings associated with data stored in record 531-1, the wireless base station 131 (or other suitable processing hardware resource) generates an interference score of 87 (high interference) for the user equipment 121-1 and respective use of a licensed wireless channel used to communicate between the user equipment 121-1 and the communication management resource 140.

In this example embodiment, processing hardware such as in a respective wireless base station or other suitable resource generates interference score between 0 and 100, in which 100 indicates a highest amount wireless interference and 0 indicates a least amount of interference.

Assume that the wireless base station 131 calculates a wireless interference score of 87 (high interference) based on the data in record 531-1.

In a similar manner, the wireless base station 131 records collected information and generates a respective interference score value for each supported user equipment.

For example, the wireless base station 131 produces record 531-2 to include feedback (link quality metrics) generated by user equipment 121-2 such as CQI (Channel Quality Indicator) value, RSRP (Reference Signal Received Power) value, RSRQ (Reference Signal Received Quality) value, RSSI (Received Signal Strength Indicator) value.

In addition to storing such feedback from user equipment 121-2, the wireless base station 131 produces the record 531-2 to include additional information such as MCS, TBS, user equipment buffer size, average data flow rate, etc., associated with the user equipment 121-2.

As previously discussed, the MCS value (MCS) is a rough indicator (metric) of wireless bandwidth capability between the user equipment and wireless base station.

Further in this example embodiment, the wireless base station 132 (or other suitable processing hardware resource) produces records associated with each of the user equipment supported by the wireless base station 132.

For example, the wireless base station 132 produces record 532-1 to include feedback generated by user equipment 122-1 such as CQI (Channel Quality Indicator) value, RSRP (Reference Signal Received Power) value, RSRQ (Reference Signal Received Quality) value, RSSI (Received Signal Strength Indicator) value.

In addition to storing such feedback (link quality metrics) from user equipment 122-1, the wireless base station 132 produces the record 532-1 to include additional information such as MCS, TBS, user equipment buffer size, average data flow rate, etc., associated with the user equipment 122-1.

As previously discussed, note that further embodiments herein include assigning either a high interference level or a low interference level to the user equipment instead of a normalized number between 0 and 100.

For example, in accordance with further embodiments, based on the threshold information provided by a respective service provider, the wireless base station or other suitable resource can be configured to assign respective user equipment a high interference score if the corresponding RSRP from the user equipment is higher than a predetermined threshold (such as previously provided by the service provider #1), and if the RSRQ value provided by the user equipment is lower than a pre-determined threshold, AND average throughput, CQI, and TBS for the user equipment are lower than a pre-determined threshold, AND average UE data buffer size is greater than a pre-defined threshold.

In yet further embodiments, the wireless base station or other suitable resource assigns user equipment a low interference score if the RSRP value from the user equipment is equal or lower than a predetermined threshold, and if the RSRQ value from the user equipment is equal or higher than a pre-determined threshold, AND average throughput, CQI, and TBS are near average or higher than a pre-determined threshold, AND average UE data buffer size is greater than a pre-defined threshold.

FIG. 6 is an example diagram illustrating determination of a region of wireless coverage for each of multiple wireless base stations and reporting of same to a communication management resource according to embodiments herein.

As previously discussed, certain user equipment in network environment 100 experiences high levels of interference. Because such devices are entitled to protected use of the licensed wireless channels (such as #11 and #12), the wireless base station or other suitable resource initiates a respective test to determine the actual region of wireless coverage associated with a respective wireless base station.

For example, in operation #7, each wireless base station (such as CBSD) calculates the number of high interference user equipment and low interference user equipment supported by the wireless base station.

For user equipment experiencing a high amount of interference (such as user equipment 121-1, 121-4, and user equipment 122-2), the respective wireless base station calculates or estimates the distance based on any suitable distance measurement test such as via sounding reference signals reported by the respective user equipment 121-1, 121-4, and 122-2 experiencing high interference.

In one embodiment, a Sounding Reference Signal (SRS) is a reference signal transmitted by the user equipment in the uplink direction which is used by the wireless base station 131 (such as an eNodeB) to estimate the uplink channel quality over a wider bandwidth. The wireless base station 131 (such as eNodeB) may use this information for uplink frequency selective scheduling.

As an alternative to use of Sounding Reference Signal to determine distance metrics, any other technique of determining a location (such as based on Global Position System information) of the user equipment with respect to the wireless base station can be used as well to determine the region of wireless coverage.

More specifically, the communication management resource 140 has knowledge and control of other communication devices in network environment 100 operating in the CBRS band. For any user equipment (such as user equipment 121-1, 121-4, and 122-2) identified as experiencing high interference levels in the allocated wireless channels #11 and #12, it is assumed that communication devices (such as wireless base stations, user equipment, etc., associated with a service provider #3) in close proximity to the region of wireless coverage 631 and 632 cause interference to service provider #1 and corresponding communication devices assigned use of wireless channels #11 and #12.

To determine a region of wireless coverage with respect to location L1, via communications 321-1 between the wireless base station 131 and the user equipment 121-1, the wireless base station 131 detects a distance between the wireless base station 131 and the user equipment 121-1; via communications 321-4 between the wireless base station 131 and the user equipment 121-4, the wireless base station 131 detects a distance between the wireless base station 131 and the user equipment 121-4; via communications 322-2 between the wireless base station 132 and the user equipment 122-2, the wireless base station 132 (or other suitable resource) detects a distance between the wireless base station 132 and the user equipment 122-2.

In one embodiment, the detected distance represents a radius (or adjusted radius) of wireless coverage with respect to the corresponding wireless base station. The radius is used to indicate the region of wireless coverage associated with each wireless base station.

In accordance with further embodiments, the wireless base station 131 can be configured to add a delta value (buffer value) to the calculated path loss and report the distance value (or adjusted distance value, radius #1) associated with the region of wireless coverage 631 to the communication management resource 140 (such as a spectrum access system). In a similar manner as previously discussed, the wireless base station 132 can be configured to add a delta value (buffer value) to the calculated path loss and report the distance value (or adjusted distance value) associated with the region of wireless coverage 632 to the communication management resource 140 (such as a spectrum access system). In other words, the calculated distance metric (radius) can be adjusted to a larger value to define the region of wireless coverage to reduce a possibility of interference.

Via communications 641, the wireless base station 131 notifies the communication management resource 140 of the actual detected region of wireless coverage 631 associated with the wireless base station 131 and corresponding user equipment.

In response to receiving communications 641 such as information indicating the metes and bounds associated with region of wireless coverage 631 as determined by the wireless base station 131 (or other suitable resource), the communication management resource 140 updates the PAL service provider information 161-2 as shown in FIG. 7 to indicate the accurately generated region of wireless coverage 631 (such as radius #1 with respect to the location L1) associated with the wireless base station 131.

Via communications 642, the wireless base station 132 notifies the communication management resource 140 of the actual region of wireless coverage 632 (such as radius #2 with respect to the location L2) associated with the wireless base station 132.

In response to receiving communications 642 such as information indicating the metes and bounds associated with region of wireless coverage 632 as determined by the wireless base station 132 or other suitable resource, the communication management resource 140 updates the PAL service provider information 161-2 in FIG. 7 to indicate the region of wireless coverage 632 (such as radius #2 with respect to location L2) associated with the wireless base station 132.

FIG. 7 is an example diagram illustrating updated wireless base station data and corresponding regions of wireless coverage based on feedback from the wireless base stations according to embodiments herein.

As further shown in FIG. 7, and as previously discussed, the communication management resource 140 records the determined/updated region of wireless coverage associated with each wireless base station. For example, the communication management resource 140 updates the PAL service provider information 161-2 to indicate the actual region of wireless coverage 631 (such as radius #1 with respect to location L1) and the actual region of wireless coverage 632 (such as radius #2 with respect to location L2).

Referring again to FIG. 6, in operation #8 the communication management resource 140 receives notification of the regions of wireless coverage as well as that the user equipment 121-1, 121-4, and 122-2 experiences high amounts of interference. Thus, the communication management resource 140 is aware that it needs to lower the power levels of any 3rd party communication devices operated in a vicinity of the calculated region of wireless coverage 631 and 632 to prevent interference to corresponding licensed users/service provider #1.

In other words, as further discussed below, because the communication management resource 140 is now aware of the actual regions of wireless coverage 631 and 632 associated with the wireless base stations 131 and 132, the communication management resource 140 prevents granting of or power levels associated with wireless channels at or around the wireless frequency associated with wireless channel #11 and #12 in a vicinity of the regions of wireless coverage 631 and 632. If needed, in operation #9, the communication management resource 140 can be configured to lower power levels of the nearby communication devices (such as wireless base station 621 and wireless base station 622 or corresponding user equipment) causing the interference to the user equipment 121-1, user equipment 121-4, and user equipment 122-2 protected by a corresponding PAL license.

As previously discussed, generation of the boundaries associated with regions of wireless coverage as described herein provides a more accurate geographical region (zone) in which corresponding PAL entities (such as wireless base station 131, user equipment 121, wireless base station 132, user equipment 122) are entitled to protection against wireless interference by other wireless users.

Thus, subsequent to defining the location and respective region of wireless coverage associated with each wireless base station, in operation #9, the communication management resource then controls allocation of wireless bandwidth (such as licensed PAL wireless channels or unlicensed GAA wireless channels) such as to wireless base station 621 at location L6, wireless base station 622 at location L5, etc., in a vicinity of the region of wireless coverage to prevent interference with wireless channels used by wireless base station 131, wireless base station 132, etc. This controlled allocation of bandwidth by the communication management resource 140 in the vicinity of the regions of wireless coverage 631 and 632 provided by the wireless base station protects use of wireless channels licensed to a respective service provider operating the wireless base stations 131 and 132.
